LOCK.

Application filed November 22, 1923. Serial No. 676,379.

To all whom t 'may concern.:

Be it known that l, DANIEL Vif. Romani, a a citizen of the UnitedStates, and a resident ot Trenton, in the county of Mercer and State ot'New Jersey, have invented a new and improved Lock, of which thetollowing is a full, clear, and exact description.

The present invention relates to new and useful improvements in lochs,and it pertains more particularly to locks of the combination type.

it is one of the primary objects of the invention to provide a new andimproved mechanism wherebyl a lock ot the sliding latch type may be usedin combination with means i'or operating the sliding latch.

It is a further object ot the invention to provide a mechanism whichwill operate in either direction without operating the latch.

ltis a further object of the invention to provide a mechanism which`will rotate in one direction without operating the latch, and, at thesame time, when properly positioned with respect to the latch-operatingmeans, will operate the latch when rotated in the opposite direction.

With the above and other objects in view, reference is had to theaccompanying drawings, in which- Figure 1 is a view1 in elevationshowing a lock constructed in accordance with the present invention, theinternal mechanism of the lock being shown in dotted lines:

Fig. 2 is a sectional View showing the mechanism ot the lock;

Fig. 3 is a sectional View taken on the line 3 3 of Fig. i;

Fig. 4 is a sectional View taken on the line li-4 oi' Fig. l;

Fig. 5 is ay detail view showing the position of certain elements of themechanism during the movement of the operating member in one direction;

Fig. 6 is a similar View showing the position of certain elements oft-he mechanism during movement o'i the operating member in the oppositedirection,

Fig. 7 shows the position of certain ot' the elements during theoperation ot moving the latch;

Fig. 8 is a detail top plan view of a portion ot' the latch operatingmember.

Referring more particularly to the drawings, the reference character l0designates a door or the like, to which the loch is adapted to beattached, and 11 designates the lock housing, which, while it is shownin the present instance as or' the mortise type, may be attached to oneot the outer faces of the member 10.

Mounted within the housing there are two spaced guides 12, and slidablymounted be 'tween said guides i2 there is a lati-h member 13, the end 14of which projects through an opening 15 in one ot the walls of thehousing 11. i spring 16, anchored as at 17', isadapted to normallymaintain this latch member in its extended position. The latch member 13is recipirocated between the guides 12, by an operating member 17pivotally connected as at 155 to the housing ll, said member 17ope-rating in a recess lt) formed in .the` latch member 13. Thisoperating member 17 is rocked about its Pivotal point 18 by means of arotating member, said rotating member 20 being carried by a shai't 21upon which there is an operating lrnob or the like, 22, secured inposition by means oit a screw 23. The shal't 2l projects through one otlthe side walls ot the housing ll, as more clearly shown in Fig. 4, andthe operating knob 22 is attached to the outer end thereof.

Pivotally connected to one of the ends of the rotating` member 20, as at25, there is a pawl 26, and carried by one ot' the sides of the rotatingmember 20, there is a spring 27 having two fingers 28 and 29. As moreclearly shown in Figs. 5 to 7, inclusive, this pawl 26 is notched out onits end, as at 30, and said notched out portion is adapted when therotating member 20 is properly positioned to engage the edge of theoperating member 17, in which position it is clearly shown in Figs. 2and 7, the spring finger 29 serving to maintain the pawl in engagementwith the operating member.

/Vith the parts in the position shown in Fig. 2, if the rotating member20 is moved to the right, the pawl 26 will rock the operating member 17about its pivotal point 18 and move the latch to the dotted-lineposition shown and permit of releasing of the locli. If, however, therotating member 20 is moved to the left or in an anti-clockwisedirection, the pawl will be disengaged from the operating member 17. Itthis member 20 is rotated a complete revolution, the pawl 26 will Wipeover the operating member 17, as is shown in Fig. 6. If With the partsin the position shown in Fig. 2, the operating member 20 is moved to theleft in an anti-clockwise direction only far enough that the paivl slipsoi the operating member 17 and is then turned to the right, the pawl 26will Wipe by the Ioperating..member i7, as shown in Fig. 5. By thisconstruction it is apparent that the only time at which the paWl iscapable of operation of the operating member 17 is When the notched part30 of the pawl is in engagement with the edge of the operating member17, and this position of the parts is determined by a predeterminedposition of the operating knob 22, it being understood that said knobcarries a plurality o calibrations in order that the position of itspawl may be determined at all times by one authorized to use the lock.

What isclaimedl is:
